Possible Causes
The AC input
voltage may be
too high.
The AC input
voltage may be
too low.
The AC output
current may be
too large.
The AC input
frequency may
be too high.
The AC input
frequency may
be too low.
The temperature
may be too low
inside the
charger.
The leakage
current to the
earth
may be too
high.
Solutions
1. Check the input voltage from
the backend.
2. If the voltage is over 253Vac
for a short time, wait till the
power supply recovers to the
normal voltage range.
1. Check the input voltage from
the back end.
2. If the voltage is under 184Vac
for a short time, wait till the
power supply recovers to the
normal voltage range.
1. Shut down the leakage current
protection, then switch off the
main power supply from the
distribution board immediately.
2. Check whether there is a low
resistance connection between
the AC output cables of the
charger.
1. Check the input voltage
frequency from the back end.
2. If the frequency exceeds
63Hz for a short time, wait
till the power supply recovers
to the normal voltage range.
1. Check the input voltage
frequency from the backend.
2. If the frequency is lower than
47Hz for a short time, wait until
the power supply recovers to the
normal voltage range.
1. Check the surrounding
conditions of the chargers
installed and whether there is a
heating device nearby. Make
sure the environmental
temperature is under 60°c.
1. Shut down the leakage current
protection, then switch off the
main power supply from the
distribution board immediately.
2. Check whether there is broken
AC output cables or low-
resistance connection to the
earth.
